Thanks dear.

Each bamboo species will be of different « quality » some are more suitable to certain instruments than others. I will be trying a thicker type of bamboo next to see the difference.

You are correct.m, the fingering is very close to the recorder. The Xaphoon is said to have a range of 2 octaves which is not bad. Mine can reach the first note of the next octave. Still working on improving this.
